I was wondering if anyone has stumbled across this situation and figured out an efficient solution or workaround.
I’ve been exploring various workflows to streamline the creation of parallel projected, technical drawings with their final destination inside Adobe Illustrator as vectors. Extracting internal lines from objects and exporting these into illustrator is fairly straightforward from an app like Rhino, using their “Make 2D” command.
The only part Rhino fails at is producing a clean, workable silhouette-outline to encompass the final illustration as a whole inside Adobe Illustrator.
The method that has been the most successful so far has been to import the geometry into C4D, and use Sketch & Toon’s ability to export sketch lines as illustrator files. The only problem is that this technique can take up to half an hour (on my computer) to generate an outline on a complex object, with all its internal lines culled. Long story short: This method works but takes a looong time to produce the outline.
Is there any alternative / faster method to produce a silhouette spline of a complex object inside C4D?
(1) One idea is to take advantage of the (instantaneously) fast orange object outline that C4D generates on selected objects. Is that data in any way “extractable” as a basis for a spline?
(2) Because the camera angle is parallel, aligning an infinite light source to it, generates a very sharp shadow onto a surface behind the object - Is there a way to use that shadow to generate the desire silhouette spline?
If you have any ideas or creative solutions to this conundrum, I’d be very interested to hear them.
